-------------------------------------
Hi Chris,
you are the best! Only your soliution was not correct, the change must be made
in TrieField (wrappedField). The problem here was a bug in the original code
(as of Lucene 1.4 / 3.1) [the same I already mentioned above]: If you created
in your Schema a TrieField with type attribute set to DATE, it behaved
differently than if you used a TrieDateField (same issue had been fixed before
in toExternal:
{quote}
TrieDateField code duplication was removed, all methods delegate to a wrapped
TrieField. There was also an inconsistency between TrieField and
TrieDateField's toExternal(). This was fixed to work correct (the date format
was wrong, now it uses dateField.toExternal())
{quote}
The correct fix is to make TrieField.indexedToReadable call DateField's
toExternal internally (like toExternal now does).

> This implements the changes to NumericField (LUCENE-3065) in Solr. TrieField
> & Co would use NumericField for indexing and reading stored fields. To enable
> this some missing changes in Solr's internals (Field -> Fieldable) need to be
> done. Also some backwards compatible stored fields parsing is needed to read
> pre-3.2 indexes without reindexing (as the format changed a little bit and
> Document.getFieldable returns NumericField instances now).
